What does amplitude modulation actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

This article attempts to provide an understanding of the electromagnetic spectrum with a focus on radio frequency (RF), optical fibers, various modulation techniques, propagation characteristics ...

Direct sequence spread spectrum Direct sequence spread spectrum (DSSS) is a form of spread spectrum modulation that is being used increasingly as it offers improvements over other systems, although ...

WAM technology is a pure digital new modulation scheme, using spectral compression that improves spectral efficiency. The spectral compression enables an increase of the signaling rate thereby ...

There are several modern digital modulation techniques that provide increased information capacity, higher data security and quicker system availability with great communication qualities.

Similarly, it's ready for RFID (RF identification) analysis, where it can analyze 2ASK (amplitude shift keyed) signals, and 2FSK (frequency shift keyed) modulation, with decoding for popular RFID ...

Press Release Light Modulators for modulation of amplitude, phase, polarization and spectrum Date Announced: 24 Jan 2011 Jenoptik is one of the few companies in the world to address the market for ...

As mobile communications become more pervasive, the amount of data flowing around the various networks and – importantly, the various parts of the spectrum – grows inexorably. The world, it is claimed ...

Having studied the case of two-level amplitude modulation, we next investigate the accuracy of CNN-based demodulation for data encoded via four-level amplitude-modulation.
